After finding this thread and reading what Zach had posted, and getting a little worried since I too had opted not to order the waste board for my 1000mm kit, I contacted the Inventables EXCELLENT customer service via email (help@inventables.com), and received the reply below. They were able to add this to my existing order, and were very prompt in their responses. Hope this helps someone else.
We have made changes to the kits since Zach
posted that answer. We made the brackets and extrusions part of the rail kit.
If you plan to make your own Waste Board we have put together the following
information for your review.
